We propose a generalized approach to the already existing crisp methods to solve the fuzzy multiattribute decision making problem. Specifically we deal with four methods, namely Simple Additive Weighting, Linear Assignment, TOPSIS and ELECTRE, where fuzzy numbers are used to represent the ratings of the alternatives and relative weights of the attributes. Through the use of fuzzy mathematics we...

This note deals with the problem of choosing on the basis of a fuzzy preference relation. In the area of MCDM, such a problem occurs with outranking methods using fuzzy relations such as ELECTRE III. In this note, we study a choice procedure based on the ‘min in favor’. We show that it is the only one to satisfy a system of three independent axioms.

In this paper, the evaluation of customers’satisfaction is investigated by using group decision making method under uncertainty. Here, we have used the Zadeh’s fuzzy concept to model and measure the satisfaction. For this purpose, we have firstly applied the Delphi method with fuzzy Likert scales. Then, the fuzzy ELECTRE technique was used in order to ordering the index and questionnaires. For ...

Abstract This article is concerned to delineate the strategic approach of ELiminating Et Choice Translating REality (ELECTRE) method for multi-attribute group decision-making (MAGDM) in terms complex spherical fuzzy sets. The feasible, well-suited, and marvelous structure set compliments efficiency ranking calibre ELECTRE I present a beneficial supreme aptitude strategy MAGDM. Beside proposed m...

The aim of this research is to propose an improved multidimensional quality life index, which could replace the current methodology designed by Eurostat and applied national statistical institutes European Union member states. novelty proposed index that it based on a non-compensatory multicriteria decision method (ELECTRE III). All other indices compensatory aggregation methods at some stage i...

Multi-criteria group decision-making is a process in which decision makers assess the performance of alternatives on the basis of conflicting criteria to opt the most worthy alternative as solution. TOPSIS and ELECTRE are effective and commonly used methods to solve multiple criteria decision-making problems. The aim of this study is to propose two new models, namely, complex Pythagorean fuzzy ...

In hesitant fuzzy sets (HFSs), which are generalized from fuzzy sets, the membership degree of an element to a set, for which decision-makers hesitate while considering several values before expressing their preferences concerning weights and data, can be assigned one or more possible precise values between zero and one. If two or more decision-makers assign an equivalent value, that value is o...

This paper presents a new fuzzy multicriteria classi®cation method, called PROAFTN, for assigning alternatives to prede®ned categories. This method belongs to the class of supervised learning algorithms and enables to determine the fuzzy indi€erence relations by generalising the indices (concordance and discordance) used in the ELECTRE III method. Then, it assigns the fuzzy belonging degree of ...

A new hesitant fuzzy set (HFS)-ELECTRE for multi-criteria group decision-making (MCGDM) problems is developed in this paper. In real-world applications, the decision makers (DMs)’ opinions are often hesitant for decision problems; thus, considering the exact data is difficult. To address the issue, the DMs’ judgments can be expressed as linguistic variables that are converted into the HFSs, con...
